SWITL -- an impressive "robot hand" tool developed by factory equipment manufacturer Furukawa Kikou -- seems to defy the laws of nature by picking up deposits of gels, sauces and other soft semi-liquids without smearing them or altering their shape. This demo video shows how well the tool handles mayonnaise and ketchup.

Details about the technology are not available on Furukawa Kikou's website (perhaps because the patent is pending), but the tool appears to incorporate a conveyor belt design. According to the company, the magic goop scoop was originally developed for use in bakery production lines, but its unique ability to cleanly handle semi-liquids makes it suitable for a wide range of applications.

It appears that the pick-up blade is a very slick (teflon) type surface which is vibrated by a piezo electric transducer at a specific frequency. This allows the blade to "levitate" the gel substance up onto the blade.
